Pat-
The only thing that was wrong with me when I was initially dx was was I needed to diet.
I went through surgery, radiation, chemo and more chemo and was on the final leg believing that I was cured and within 4mths of treatment it's in both lungs.
I DON'T BELIEVE IT! I still stink it's something else. BUT the doctors say we have to provide it. The additional stains and testing I had done from my initial surgery did confirm (again) that it is lung cancer. We can't get any samples of the new stuff, it's in bad places. They would have to stop my breathing to get a piece of it and don't want to do it.
Have the pathology slides read by several people, have another bioipsy done if you want, I do understand your feeling though. PM me if you want to talk more!
